GAS-GENERATING APPLIANCE.

Application filed October 21. 1921. Serial No. 509,305.

burners, so far as I am advised, to associate suitable preheating or self-heating means therewith in order to convert hydrocarbon fuels intoga'seous or vaporous form, and such means arenot adapted for close regulation nor for instantaneous or intermittent Accordingly, 'I have provided suitable apparatus, preferably'electrically heated, for direct or intimate association with any'suitable gas burner or group of gas burners of compact,non-regenerative type, whichwill convert the fluid fuel into gaseous or vaporous form just as it'i'sfed to the burner. More over, the independentmeansprovided forheating the fluid 'fuel' are adapted for immechute and intermittent 'u'seywhile"affording the closest possible regulation, This apparatus is simple and cheap in construction, coupled with a'low'cost ofoperation.

Briefly describing the embodiment of in Y invention herein showngIma'y state that it comprises an elongated feedin chamber to which the fluid fuel is fed and a out which is disposed an electrical heating unit which is adapted to maintain the feeding chamber at a sufficiently high temperature to volatilize or render vaporous any suitable hydrocarbon fuel supplied to said chamber. The details of the preferred constructions may more readily be explained by making reference to the accompanying drawings, wherein:

Figure 1 is a. view in vertical section showing the simplest form of gas-generating appliance embodying my improvements.

Fig. 2 is a bottom view thereof.

-""' Fig. 3 is a rear elevation, partially 1n section on line 3-3, Fig. 1.

Fig. 4 is a front elevation thereof, and

Fig. 5 is a longitudinal sectional View of a modified appliance adapted to preheat the Throughout the several figures of the drawings I have employed the same characterof reference to indicate similar parts.

Referring first to Figure 1, the casing a is provided with a rectangular air inlet a and an openlng a opposite the extended end of the feeding chamber 6. This feeding chamber is of elongated tubular form and rearwardly connects with a controlling valve 0, while forwardly itis provided with a small opening or perforation b interiorly guarded by the protruding nipple b.

The purpose of the nipple b is to afford a free exit for the generated gas within the feeding and heatin chamber 6, since the opening thus guar ed-is not likely'to be clogged by the slight accumulation of carbon within the chamber, Instead, this carbon wil deposit in small quantities about the base of he nipple unt-il t-he chamber is opened and cleaned.

It' will be noted that-the chamber 6- sur roundedby coils of resistance wire 01 which are supported longitudinally Within the tubular sectionof the casing by the spaced lava members 6 which are suitably perforated to accommodate the coiled wire-and-are held rigidly by'me'ans-o'f'the' threaded rods e and nutse.:

Thel 'combinedfeedingand heating chainbr b with'its controlling valve c'ismounted; asa unit rear'wa'rdly of the casing'by means of the angularly extending steni e and its nut c whic'his clamped down" upon the slotted extension a for thepurpose'of hold-= ing the valve and chamber in place. A centrally perforated cover f normally protects the exposed portions of the resistance Wire which terminate at the contacts (1, (1 through which current is supplied thereto, as desired.

From the foregoing it will be readily understood how the heating chamber may be inserted and removed from the casing in order to inspect or clean the same. This is accomplished simply by removing the nut c and the connected feed pipe (not shown) whereupon the cap 6 may be unscrewed and any accumulated carbon or other deposit will be readily removable therefrom.

Referring further to the modified construction as shown in Fig. 5, the details already explained are essentially duplicated therein. However, the casing a* is suitably cored to provide a surrounding annular chamber a for the fluid fuel, whereby it may be heated from the enclosed electrical heating unit; connection being made from the feed pipe 9 and through the preheating chamber a and p pe g to the controlling valve 0. The preheating chamber is rearwardly closed by the annular member a.

The electric heating unit, although of equivalent construction, varies somewhat in detail; comprising a hollow lava core h suitably recessed a-nd grooved mzacwmmodate the coiled resistance w'ue d, The terminals of this wire are shown to be suitably insulated by lava beads h; with which wire are diagrammatical-1y associated a combined switch der pressure to and resistaute coil or rheos ta-t i and source of current k.

The fluid fuel, either at normal .or preheated temperat-u me, upon being supplied unthe combined feeding and heating chamber of my improved dep'ice, 15 immediately converted into a gaseous or vaporous form and diseharged through the 0121- fice b and onto an associated burner (-not shown) carrying with it the supply of all ne ly r p1 .i nstmot enan lisca able oiiassocea m i alarge rangeoi gas: n: e155 for various uses.

. rea ms Moreover, the current n'lay be readily reg-- ulated so that the temperature of the feeding and vaporizing chamber shall not exceed the carbonizing temperature of the particular fuel employed, whet-her crude or refined oils; all entirely independent of the rate at which the fuel is being burned from time to time.

The embodiments of my invention, as shown herein intimately associated with what I may term a non-regenerative burner of the simplest and most compact tg pc, permit the burning of the liquid fuel in vaporous form and at a low temperature, which would be impracticable if the vaporized .fucl were conducted to a relatively distant btu'ner and thereby subjected to cooling or condensation. Again, the self-heating or regenerative adjunet-s of the burner are lacking and permit my device to be used in positions where the space available for the burner is restricted.

Having now described the preferred embodiment of my invention, I claim as new and desire to secure by Letters Patent, the following:

1. Luapparatus of the class described, the combination with a supporting casing, of a removable electrical heating element, and an associated removable vaporizing chamber, both adapted to be inserted within said casing in operative relation, and a controllable fuel supply connection for the vaporizing chamber;, substantially as set forth.
